The Constitution provides that the president, vice president and all civil officers of the United States, shall be removed from office on impeachment for, and conviction of “Treason, Bribery, or other high Crimes and Misdemeanors.” No definition of high crimes and misdemeanor is given in the Constitution, but the Congress -- and the US Supreme Court -- has generally taken a very wide view of this injunction. Of the 19 officers impeached in the US, 15 have been judges and so have been all the eight removed by the Senate. The Senate has only voted to bar three officers from any further office.
